Application filed June 6, 1901. Serial No. 63,3443. (N0 model.)

To It, wltom it may concern: 1

Be it known that I, TnoMAs SrnNonR MIL- LER, a citizen of the UnitedStates, and a resident of South Orange, in the county of Essex and Stateof New Jersey, have invented a new and Improved Hoisting Device, ofwhich the followingis a full, clear. and exact description.

My invention relates to an improvement in hoistingdevices adapted totransfer goods, as from a vessel to a dock and other similar locations,and is especially designed for use in unloading coal and similarmaterial, although it is equally applicable to use in handling otherforms of material.

My invention comprises novel features, which will be hereinafterdescribed, and particularly pointed out in the claims.

Figure 1 shows in front elevation two of my hoisting devices. Fig. 2 isan elevation of one of my hoisting devices, taken from the side or atright angles to that of Fig. 1. Fig. 3 is a plan view omitting the mastsO and the ropes and other parts supported thereby. Figs. 4 and 5 areelevations at right angles, showing the elevated traveler or guide forthe hoisting-rope. Fig. 6 is an elevation of the drum used forcontrolling the position ofthe boom.

My device is herein shown and will be described as employed for hoistingcoal, ore, and similar material from a boat and deposit ing it in carsupon a dock. From this description its other uses will be evident.

In Fig. 2 a boat V, from which a load of coal or other similar materialis to be taken, is shown as lying alongside a dock A. In the case shownthe coal is to be delivered into cars O, which run upon one or moretracks G, extending parallel with the side of the clock. In this casethe cars run upon an elevated structure a, as for coal-storage plants itis desirable to have the coal delivered at considerable elevation. Thiselevated structure carries tracks a, which lie outside of the tracksoccupied by the cars while loading.

A platform B, upon which the hoisting-engines and other apparatus usedin handling the material are placed. are supported above the tracks O,which carry the cars, by legs 5, said legs carrying Wheels I), which runupon the tracks a, so that the device may be moved along the (lock toany point where it may be needed. Of course where employed upon adifferent kind of work and under different conditions the elevatedstructure and the supporting-legs of the platform B may be dispensedwith or modified. 1 have also shown the elevated structure as located ashort dis tance back from the edge of the dock; but it is evident thatit may be advanced to the dock margin, if desired.

Upon the platform or car B are mounted three rope-winding mechanisms andmeans for operating them independently. These mechanisms, as hereinshown, consist of the drums (Z, d, and (Z the engines D and l). and theboiler I for supplying them with steam. The drum (6 carries thehoisting-rope G, the drum (Z carries the load-swinging rope F, and thedrum (Z the boom-hoisting rope H.

The drum d is an ordinary friction-operated drum, and in many cases thedrum d would. be of the same character, although where the bucket orload being hoisted is to swing back beyond the point of support of thehoisting-rope it might be desirable to have this drum reversible. Such acondition is shown in Figs. 2 and 3; but the swing of the bucket beyondits point of support is obtained by using a counterweight.

The drum (Z which carries the boom-hoisting rope, may be operated in anyconvenient manner, either by hand or by power, altl'iough I prefer apower connection. Such a device is shown in Fig. 6. The drum (Z isloosely mounted upon the shaft U of the drum (Z or any shaft which maybe turned from the engine. A clutch (or equivalent device) composed ofthe two parts S and S, secured one to the drum and the other to slideupon but turn with the shaft U, is operated by a lever S so that thedrum may be turned to wind up the rope when desired. Ratchetteeth T anddog T are provided, by which the drum may be held against backwardrotation.

Pivoted to the car or platform li is a boom E, which is shown as havingtwo side members, each of which is secured to the platform B at one sideof the vertical plane in which the fall-rope swings, so as to be out ofthe way of said rope and the load carried thereby. These side memberspreferabl y incline to ward the swinging-rope F and are provided attheir outer ends with a cross-bar, to which is secured the sheave f,constituting the tail-guide, over which passes the swinging-rope F. Thisrope is herein exemplified as an endless one, winding upon one side ofthe drum d as it winds off of the other side; but I do not wish to limitmyself to the endless form. One run of this rope leads oververtically-placed guidesheaves 7r, carried by a bracket K, and thenceleads beneath a sheave Z from which is suspended the counterweight K,which is shownto exemplify herein a form of tension device for the ropescontrolling the guide L. The other run of this rope passes over thesheave f at the outer end of the boom and then back to a guide L for thehoisting-rope, the other run of the load-swinging rope connecting withsaid guide from the opposite direction. This guide consists of a framecarrying two pulleys or sheaves L, between which the hoisting-rope runs.

Extending in a row alongside of the path of travel of the car orplatform B are a series of posts or masts O, which support atrackway-cable N, the cable at the ends of the series extending downwardto anchorages or the end masts being provided with corresponding guys,as at a. Upon this trackway-cable, between each pair of masts, is placeda traveler or movable support for the sheaves carrying the boom-hoistingand load-hoisting ropes. This is shown in Figs. A and 5. This consistsof a frame, as I, in which is mounted a single sheave 19, adapted to runupon the trackwaycable, and two sheaves g and /L at right angles tosheave 1), designed to receive the boom-hoisting rope H and theload-hoisting rope G. To the frame and extending oppositely are attachedtwo traveler moving or steady ropes Q, which pass over sheaves R at thetops of the mast and then down to hand-winches Q. By these means thetraveler may be moved to and held in any position on the trackway-eableand may thus be made to correspond with the position of the car B.

The iioor of the platform or car B has openings in line with the swingof the bucket M and hoppers 6 through which the coal may be dischargedinto the cars G beneath.

It is evident that by sufficiently extending the bracket K so as to actas a boom my device may be employed for transferring goods from a boatto a car or dock at the side of the device opposite that where the boatis. In such case it might be advisable for convenience to pivot the boomwhich corresponded with the bracket K. In the condition shown thebracket K is a short fixed boom. \Vith such a construction it wouldprobably be dosirable that the engine D be reversible or the drum (Z beconnected thereto, so that it might be reversed.

As shown in Figs. 2 and 3, the bucket M is caused to swing to itsdumping position by the action of the counterweight. The counterweightis useful also to take up slack in the rope F, especially when the boomis raised. In case two booms were used extending oppositely thecounterweight might preferably be located otherwise than at the outerend of the boom.

The operation of my device is as follows: The car or platform B iscaused to travel along its tracks until opposite the point from whichthe loads are to be raised. If the ropes Q are loosened, the travelerwill be moved to nearly the same point. By means of the ropes Q, thetraveler may be properly placed and made fast. To hoist, the guide L forthe load-hoisting rope is moved outward to the proper position bypulling in upon the lower run of the swinging rope F. i The bucket M isthen lowered and when filled is hoisted, the rope F being operated toswing the load inward either while hoisting or after the bucket has beensufficiently raised. Unless the bucket may be permitted to drop somewhatwhile swinging in, the rope G must be drawn in somewhat while swingingthe bucket in. When the bucket reaches the proper position, it is dumpedinto the hopper.

One important feature of my invention consists in the fact that theguide L is rope-supported, and although I have shown it as supported bythe rope F, by which it is also moved, I do not wish to be limited tosupporting it by ropes in this position or necessarily by the same ropesby which it is moved. Among the advantages of having the guide Lrope-supported may be mentioned the fact that thereby is obviated anydisaster from collision between the bucket and the guide should thebucket either by carelessness or intention be raised higher than thenormal position of the guide, the flexibility of the rope supportpermitting the bucket under these conditions to push the guide L upwardwithout disaster. Another advantage of the rope support consists in thefact that thereby the apparatus may be rigged largely of ordinaryrigging appliances.

Another important feature of my invention consists in the fact that theruns of rope F operating and supporting the guide L are undersubstantially constant tension, and although I have shown thecounterweight K as the tension device for this purpose I do not wish tobe limited thereto. Among the advantages of such tension are the factthat the definite track, and a hoisting-rope, of an elevated trackwaysubstantially parallel with the direction of movement of the engine, aguidesheave for the hoisting-rope adapted to be supported from and to bemoved along said elevated trackway, and steady-ropes extending from saidsheave toward each end of the trackway.
